For individuals with obsessive-compulsive disorder (OCD), family accommodation of symptoms, such as over-reassurance, participation in rituals, or facilitation of avoidance, is one of the key factors associated with symptom severity, maintenance, and related impairment. Most studies have assessed accommodation behaviors based on reports from family members or other loved ones. Recently, a patient-rated questionnaire, the Family Accommodation Scale for OCD-Patient Version (FAS-PV) was developed to assess family accommodation from the patient's perspective.

Mental healthcare professionals often have limited awareness of different obsessive-compulsive disorder (OCD) symptom presentations, which may contribute to years between OCD symptom onset and treatment initiation. While research has identified high rates of OCD misdiagnosis among clinicians from the United States and Canada, research on OCD symptom awareness among healthcare providers in Latin American (LATAM) regions is limited. In this study, LATAM mental healthcare providers ( = 83) provided diagnostic impressions based on five OCD vignettes: three with symptoms centered on taboo thoughts (sexual, harming others, and religion/scrupulosity) and two about contamination or symmetry obsessions.

Childhood adversity and anxiety have been associated with increased risk for internalizing disorders later in life and with a range of brain structural abnormalities. However, few studies have examined the link between harsh parenting practices and brain anatomy, outside of severe maltreatment or psychopathology. Moreover, to our knowledge, there has been no research on parenting and subclinical anxiety symptoms which remain persistent over time during childhood (i.

Background: Cognitive-behavioral therapy (CBT) is the gold-standard psychotherapeutic treatment for pediatric negative valence disorders. However, some youths do not respond optimally to treatment, which may be due to variations in neural functioning.

Methods: We systematically reviewed functional magnetic resonance imaging studies in youths with negative valence disorders to identify pre- and post-treatment neural correlates of CBT response.

Deep transcranial magnetic stimulation (dTMS) has emerged as a treatment option for adults with obsessive-compulsive disorder (OCD) who continue to exhibit impairing symptoms following an adequate response to first line interventions. Currently, little is known about the predictors or moderators of dTMS outcome for OCD. This paper examined if several theoretically relevant variables may predict and moderate treatment effects including OCD symptom severity, functional impairment, co-occurring depressive symptoms, age, gender, age of OCD onset, and family history of OCD.

Chronic pain in adolescents can be highly impairing. Parental reactions to their child's pain are important factors influencing pain perception and pain-related impairment in children and adolescents. The present study aimed to examine parental accommodation of pain symptoms using the Inventory of Parent Accommodations of Children's Symptoms (IPACS) to provide empirical support for the utility of this measure in parents of adolescents with chronic pain.

The impact of externalizing comorbidity on treatment outcome was examined in 104 youth ages 7-16 (M = 11.09 years) with autism spectrum disorder and primary anxiety/obsessive compulsive disorder who completed modular cognitive behavioral therapy (CBT) for anxiety/OCD. Three comorbidity profiles were utilized for group comparisons: participants with oppositional defiant or conduct disorder with attention-deficit hyperactivity disorder (ODD; CD; ADHD; group EXT, n = 25); those without ODD/CD and only ADHD (group ADHD, n = 46); and those without externalizing comorbidity (NO-EXT, n = 33).

Little is known about the predictors of outcome from intensive residential treatment of OCD. This study aimed to examine age, gender, and baseline OCD severity, as well as measures of comorbid anxiety and depressive, internalizing/externalizing, and inattention symptoms, as predictors of treatment outcome in adolescents receiving intensive residential treatment for OCD. The sample comprised 314 adolescents aged 13-17 years with treatment-resistant OCD and a Children's Yale-Brown Obsessive-Compulsive Scale Self-Report (CY-BOCS-SR) total score ≥16.

Previous studies have reported altered fear circuitry function during fear conditioning in highly anxious individuals and in adults with a history of severe childhood adversity; less is known regarding younger populations and more common forms of adversity. We investigated fear circuitry functioning in healthy youths with histories of high (HH) or low (LH) chronic harsh parenting and high (HA) or low (LA) anxiety levels. 84 youths aged 13-16 performed an fMRI fear conditioning task.

Patient behaviors that may interfere with the process and outcome of therapy have been examined in the context of dialectical behavior therapy, but no measures exist to systematically characterize patient (or caregiver) treatment interfering behaviors (TIBs) in cognitive behavioral therapy (CBT) for anxiety disorders and obsessive-compulsive disorder (OCD). Accordingly, the primary aims of this study were to develop preliminary measures of TIBs, asking clinicians who provide CBT for anxiety disorders and/or OCD to adults and/or children to retrospectively reflect on the presence of TIBs in a recent patient (or caregiver of a child patient). These measures assessed the presence of 27 adult patient and 34 caregiver behaviors that may have interfered with treatment.

Background: Body-Focused Repetitive Behaviors (BFRBs), including skin-picking, hair-pulling, and nail-biting, commonly occur in youth, even at elevated/problematic levels, and are associated with a number of other psychiatric symptoms. The present study examined the internal consistency of a brief screening tool for BFRBs as well as the prevalence, severity, and correlates of BFRBs in a sample of youth with a primary anxiety or obsessive-compulsive disorder (OCD).

Methods: Ninety-three youth-parent dyads presenting for treatment for anxiety or OCD completed study measures including the Repetitive Body Focused Behavior Scale - Parent (RBFBS), which includes subscales for skin-picking, hair-pulling, and nail-biting, as well as a number of additional clinician-, parent-, and child-rated scales.

Adult work shows differences in emotional processing influenced by sexes of both the viewer and expresser of facial expressions. We investigated this in 120 healthy youths (57 boys; 10-17 years old) randomly assigned to fear conditioning and extinction tasks using either neutral male or female faces as the conditioned threat and safety cues, and a fearful face paired with a shrieking scream as the unconditioned stimulus. Fear ratings and skin conductance responses (SCRs) were assessed.

Anxiety can either impair or enhance performance depending on the context. Increased sensitivity to threat seems to be an important feature of sensory processing in anxiety since anxious individuals tend to be more attentive to threatening visual stimuli. Evidence of anxiety effects in olfaction is rare; though alterations of olfactory performance in psychiatric patients and some effects of trait and state anxiety on olfactory performance have been reported.

Cross-modal interactions between vision, audition and touch have been extensively studied in the last decade. However, our understanding of how the chemical senses interact with other sensory modalities remains relatively scarce. We performed a cued auditory localization paradigm in healthy young adults by measuring reaction times to monaural auditory stimuli after subjects had been cued by unilateral olfactory stimuli, mixed olfactory/trigeminal stimuli or somatosensory stimuli.

Odor stimuli presented to one nostril can only be localised if they additionally activate the trigeminal nerve's chemosensitive fibers. In this study we aimed to investigate characteristics in the localisation of unilateral trigeminal, olfactory and somatosensory nasal stimuli. We compared the ability of healthy young subjects to localise monorhinally presented (a) pure olfactory stimuli (phenyl ethyl alcohol), (b) mixed olfactory trigeminal stimuli (eucalyptol), and (c) somatosensory stimuli (air puffs).
